Two movers push horizontally on a refrigerator. One pushes due north with a force of 150 N and the other pushes due east with a force of 200 N. (a) Find the direction and magnitude of the resultant force on the refrigerator. (b)Show that the result of the previous problem is independent of the order in which the forces are added.

|F| = sqrt (150^2 + 200^2)

tan theta = 150/200 (angle north of east)
